When decks must become crop-friendly visuals
Marketing squads treat exported slide PDFs as master canvases before slicing hero images, short-video tiles, and MOOC cover frames—PNG preserves gradients and glyph edges better than lossy JPEG chains under repeated compression. Widescreen decks oscillate between cinematic monitors and brutal vertical crops; low DPI exports stair-step headline type while oversized PNGs choke collaboration drives. Hidden slides, speaker notes, and video placeholders behave inconsistently across authoring apps, creating phantom “missing pages” anxiety during automation. Ai2Done lets you pin ranges, clarity targets, and explicit progress inside the browser—pilot the branded gradient opener and data-dense chart slide before generating the full syllabus pack. Validate crops inside real channel masks afterward; pad layouts upstream instead of stretching raster slices when Instagram-safe zones disagree with keynote proportions. Animation-heavy storytelling still belongs to video exports—PNGs snapshot states, not transitions.
Slide PDF→PNG in three steps
- Decide whether hidden slides or notes layers belong in scope.
- Pick DPI/dimensions tuned to placement channels; pilot hero slides first.
- Batch-export, then review inside authentic crop templates before handoff.
